The diaphragm accumulator contains elastic diaphragms that can deform when the fluid pressure fluctuates, thereby absorbing and storing part of the pulsation energy. When the pressure peak passes, the diaphragm gradually returns to its original state, slowly releasing the stored energy, thereby smoothing the output of the fluid pressure. In pneumatic diaphragm accumulators, inert gases such as nitrogen are used as energy storage media. When the system pressure fluctuates, the gas is compressed or expanded, which plays a buffering role and reduces the direct transmission of pressure pulsations.
The diaphragm accumulator can store energy when the system pressure is high and release energy when the system needs it (such as when the pressure drops), thereby maintaining the stability of the system pressure and avoiding pulsation caused by sudden changes in pressure. By adjusting the volume and charging pressure of the accumulator, the fluid flow can be regulated, making the fluid output more stable and reducing the pulsation caused by sudden changes in flow.
Pulsation is often accompanied by shock and vibration, which can damage the components in the hydraulic system. The use of diaphragm accumulators can effectively reduce these shocks and vibrations, protect system components from damage, and extend service life. By reducing pulsation, diaphragm accumulators also help improve the overall efficiency of hydraulic systems. Because pulsation causes energy loss and system heating, the use of accumulators can reduce these unnecessary energy losses and make the system more energy-efficient and efficient.
In emergency conditions, when the hydraulic or fluid system suddenly encounters a surge in load or needs to respond quickly to provide additional power, the diaphragm accumulator can quickly and effectively play its key role. The pre-charged gas or compressed fluid inside it stores considerable energy under high pressure. Once the system sends a demand signal, this stored energy can be released through the rapid deformation of the diaphragm, converted into an instantaneous pressure pulse or flow increment, and directly provide the necessary power support for the system. This rapid response capability not only helps the system quickly overcome sudden loads and avoid possible downtime or failures, but also ensures the continuity and stability of system operation in emergency situations. At the same time, this feature of the diaphragm accumulator also reduces the immediate dependence on the main power source, provides additional safety redundancy for the system, and further enhances the reliability and resilience of the system.
The diaphragm accumulator effectively reduces pulsation in hydraulic or fluid systems and improves system stability and efficiency through its unique structure and working principle. At the same time, it also has many advantages such as protecting system components, energy saving and high efficiency, and responding to emergencies. It is one of the indispensable and important components in hydraulic systems.
